IiKholamu eziNtathu zeNkqubo yeDistillation yoxinzelelo oluNinzi
Isishwankathelo
I-five-tower-three-effect yiteknoloji entsha yokonga amandla eyaziswa ngesiseko sesiqhelo se-distillation ye-distillation ye-five-tower-tower, esetyenziselwa ukuveliswa kotywala bezinga eliphezulu. Ezona zixhobo ziphambili zokwahluka koxinzelelo lwendalo ezineenqaba ezintlanu ziquka inqaba ekrwada yokuhluza, inqaba yokuxutywa, inqaba yokulungisa, inqaba yemethanol, kunye nenqaba yokungcola. Indlela yokufudumeza yeyokuba inqaba yokulungiswa kunye nenqaba yokuxutyushwa ifudunyezwa ngumphunga ophambili kwisixhobo sokubuyisela, kwaye umphunga wewayini wokulungisa uhambisa ubushushu kwinqaba ekrwada yokuxutywa kwe-distillation ngokusebenzisa i-reboiler. Umphunga wewayini we dilution tower unikezela ubushushu kwinqaba yemethanol ngereboiler. Inqaba yokungcola isebenzisa umphunga othe ngqo ukubonelela ubushushu ngokuthe ngqo, kwaye ukusetyenziswa komphunga kukhulu. Esona sixhobo siphambili se-five-column three-effect differential pressure distillation ikwayi-crude distillation tower, i-dilution tower, i-rectification tower, i-methanol tower, kunye ne-tower yokungcola.
Okwesibini, iimpawu zenkqubo
1. Inkqubo yokudibanisa i-thermal enempembelelo emithathu yokufudumeza i-dilution tower, i-de-methanol tower, inqaba yokungcola, kunye ne-diluting tower kunye ne-de-methanol tower ukufudumeza i-distillation tower ekrwada ukunciphisa ukusetyenziswa komphunga. Ukuveliswa kweetoni zokusetyenziswa kotywala kwibakala eligqwesileyo yi-2.2 yeetoni.
2. Icandelo le-degassing kunye ne-separator zilungiselelwe kwindawo ephezulu ye-crude distillation tower ukunciphisa ukungcola okufana ne-solids equlethwe kwi-alcohol ekrwada engena kwinkqubo yokulungiswa, ngaloo ndlela iphucula ukucoceka kotywala obungcolileyo.
3. I-reboiler ye-crude distillation tower ithatha iteknoloji ye-patent ye-thermosyphon circulation heat endaweni yemowudi yokufudumala yokujikeleza okunyanzeliswayo, kwaye umphumo wokulondoloza amandla uyamangalisa, kwaye i-blockage phenomenon ye-reboiler yokutshintsha ubushushu iyacinywa.
4. Ukupakishwa kombhobho wobhedu kongezwa kwisistim sokucoca ukuphucula umgangatho wokunambitheka kotywala obugqityiweyo.
Okwesithathu, indlela yokufudumeza
Isitshixo ekugcinweni kwamandla kule nkqubo yindlela yokufudumeza kwayo, apho i-steam ephambili idlula kwi-reboiler ukutshisa ikholomu yokulungiswa. Idistillation tower yewayini umphunga unikezelwa kwikholamu yemethanol kunye netower dilution ngokusebenzisa irebhoiler yekholomu yemethanol kunye nekholamu yokudibanisa reboiler. Idilution tower kunye ne-methanol tower vapour yewayini ngokulandelelanayo zidluliswa kwikholamu ekrwada yokugalela izibiliboli zerebhoilers A kunye no-B ukubonelela ngenqaba ekrwada yokuhluza. Inqaba yokuchithwa kwenkunkuma amanzi amdaka akhanyisa umphunga ukuze abonelele kwinqaba yokungcola. Inqaba enye ingena kumphunga kunye neenqaba ezintlanu ukuphumeza ukudityaniswa kwe-thermal enempembelelo emithathu ukufezekisa iinjongo zokonga amandla. Ukuveliswa kweetoni zokusetyenziswa kotywala kwibakala eligqwesileyo yi-2.2 yeetoni.
Okwesine, umkhwa wezinto eziphathekayo
Imash evundisiweyo evuthiweyo ityiswa ukusuka phezulu kwikholamu yedistillation ekrwada emva kwezigaba ezibini zokufudumeza. Umphunga wewayini ongaphezulu kwinqaba ekrwada yokuxutywa kwenkunkuma uyajikwa emva koko uxutywe kwaye ucocwe ube yidilution tower ukunyibilikisa utywala obukrwada ukuya kwi-12-18% (v/v). Utywala obuphantsi bufudunyezwa kwangaphambili kwaye bungena kwinqaba yokulungiswa kumgca wecala eliphezulu lekholamu ye-distillation. I-alcohol (96% (v / v)) ikhutshelwa kwikholamu ye-de-methanol ukususa ngakumbi ukungcola okufana ne-methanol, kwaye utywala obugqityiweyo bukhutshwa phantsi.
Ezinye iingenelo
1. Ngokubhekiselele ekugcinweni kwamandla, indlela yokufudumeza i-thermosiphon reboiler cycle ithathe indawo yemowudi yokufudumeza okunyanzeliswayo, kwaye isebenzisa iteknoloji yethu enelungelo lobunikazi ukuphepha ukuvinjelwa kwe-tube yokutshintshiselana kobushushu. Ukusetyenziswa kotywala ngetoni yotywala ngama-20kwh. Xa kuthelekiswa nokuphuculwa kwe-distillation ye-distillation ye-tower emihlanu yokuqala ye-distillation ye-40-45kwh, ukugcinwa kwamandla ngama-50%, okuthintela ukugcinwa kwepompo yokujikeleza ngenkani kunye nokwandisa ubomi benkonzo ye-reboiler.
2. Ukunyangwa kwewayini engcolileyo: Utywala obungcolileyo obuvela kwinqaba ye-distillation ekrwada, i-dilution tower, i-methanol tower, njl., kunye newayini ekhanyayo evela kwi-fusel separator ye-oyile ingena kwinqaba yokungcola, kwaye utywala obunxilisayo bukhutshwa emva kokuba i-condenser ye-tower yokungcola iphelile. I-oyile yefuseli iyatsalwa, kwaye utywala obukrwada obuthatyathwe kumgca wecala elingasentla emva koko bugqithiselwe kwi-dilution tower ukuze kwandiswe isivuno sotywala somgangatho ophezulu.
3. Ngokubhekiselele ekuphuculeni umgangatho wotywala, ngaphezu kwemilinganiselo yezobuchwepheshe, isakhiwo sesixhobo siphuculwe. Inqaba ye-distillation ekrwada ixhotyiswe ngesixhobo sokucoca iwayini ekrwada, kwaye inqaba yedistillation ibonelelwa ngesixhobo sokususa i-copper filler sulfur ukuqinisekisa ukucoceka kunye nencasa yotywala.
Okwesithandathu, umgangatho ogqwesileyo wokusetyenziswa kotywala kunye netheyibhile yokuthelekisa umgangatho.
